ABSTRACT

Hypothesis: To investigate the feasibility of gene therapy of the n"riddle ear rlluco$a using a :rovel vector" Background: lnsofar as presenl medications are inadeqate to address chror:ic otitis merjia, cholesteatonra, or tyrrrpanic membrane ;:erforation, newer melh- orJs of treatmEnt for these diseases, such as gene therapy, need be explored. Cenes cor-rld be usecl to alter cytokines irr thtl middle ear, slcw or stop choles- teatoma growth, or improve tyrnpanic menrbrane perforation healirrg. Fellintl immunodeficiency virus (FlV), a new lentiviral vecior, has heen found to have grerate r ihan 9Clol, e{ficacy in transfecting epithelial cells. Thereiore, in vivo gene therapy of midrJle ear mucosal cells was attempted. Methods: Twenty microliters of 107 vectr:rs/mL FIV carrying the gene ior green flur:rescence protein (CFP) was introduced into the middle ears of Sprague-Dawley, rats via a Liulla approach. R.esults: [xpression oi the CFP gene was observed in the nricldle ear n:ucersal cells, indicating transfection.

Dtnnis S. Poe, M.D., Aslwaf A. Halnwn, M"B,B.Ch., M.5., nnd Osams A. Razek, M.B,B.Ch., M"S.

ABSTRACT

Objective: Human eustar:hian tubes (ETs) with lcnown ear pathology were inspected endoscopically and video recordings were made for slow-motiorr analysis of pathophysiology. Setting: Ambulatory office in a tertiary referral center. $ubjects: Forty-four adults with 64 pathological ears" lnterventians: Transn;lsal endoscopic examination of the nasoplraryngeal opening of the ET during rest, swallowing, and yawning tc stLrdy ET dilatory move ments. Main outcome Measures: Slow-motion video analysis of ET opening nlove- ments" Results: Sixty-four pathological ears and ETs ltere studied. Tubal {r,rnction was gracled on: I . [xtent of lateral excursion and progression of dilatory wave as estimates oi tensor veli palatini arrd dilator tubae muscle iunction. Reduced funciion was observed in 43 tubes. 2. Degrce of mucosal disease, which was significant in 48 tubes. 3. Polypoid or other obstructive mucosal changes, present in l5 tubes. 4. Ease and {requency of tubal operring with maneuvers: 26 tubes opened moderately, 21 opened minimally, and 11 were unable to open" 5. Patulous tubes. All 6 clinically patulous tubes showed conc;:rvities in the superior third oi the tube, which is convex in normals. All tul:es with active ear palhology (otitis rnedia with effusion, tympanic membr;rne retractiot-t, drairring ear, cholesteatonra) had significant ahrrormali- ties. Correlation could not be rnade between the severity of middle ear disease and the severity of observed ET dysfunction. Conclusions: Slow-motion endoscopic video analysis was a useful techr:ique in classifying typos of ET pathology. Additiorral str-rdies of dysfunctional tr,rbes are needed to predici outconres irr operative ear cases and to design intratubal therapy for chronically dysfunctional tuhes.

LASTR STAPTDOTOMY WITH CONSIRVATION OF THE STAPEDIAL TTN DON

Railney C. Perkins, M.D.

ABSTRACT

Olriective: The objective of this study was to develop a procedure that allows the siapedial tendon to l-:e conserved in the surgical correction of otosclerosis, and to assess the results. Conservation of the tendon theoretically should prcl- vide protection against noise trauma in this group of patients. Study Design: Patients in wlrom the proceclure was done were studiecl pro- sp*ctively. Setting: Surgery was performed in an ambulatory surgical center, with pre- and postoperative studies dorre in an outpatient clinic. Patients: Patients who had clinical o{osclerosis and who were c:rndidates for silrgery were selecled for the study. lnterventions: Patients in the study group underwent laser stapedotonry with conservation of the stapedial tendorr. The procedures were done under local analgesia on an outpatient basis" Main Outcome Measures: Audiometric improvement in hearing and main- tenance of stapedial reflex on impedarrce aurliometry were assessed. Air con- duction, bone conduction, and speech discrimination testing and impedance audiometry were per{ormed pre- and postopelatively. Results: Audiometric resLllts were comparable with results in contrr:l patients who had undergone conventional laser stapedotomy with vaporizalion oi the stapedial tendon. The stapedial reflex could be demnnstraied postoperatively in the study group. Tl'rere rl,as no evidence o{ adverse effect, increasecJ cost, or significantly increased surgical tirne, and there was no increase in morbidity. Conclusion: The technique provides a method for conserving the stapedial tendon in patients undergoing laser stapedotomy for atosclerosis. ln these pa- tients it is expectecl that ihe protective function of the stapedial reflex will be maintained.

VIBRATORY SAMPLE MACNTTOMETRY OF STAPIS PROSTHHSES TO ASSESS MR SAFETY AND COMPATIBILITY

Mark l. Sqws, M.D., {}nil Dercick W. Peterman, Pfu.D.

ABSTRACT

Objective: To assess lhe ferrcmagnetiviiy of stapes prustheses using a vihra- tory sanrple nragnetometer {VSM)" Data Sources: Previr:usly, stapers prostheses from different manu{aclurers were placed in a 1 "5-tesia MRI field to determine their ferromagnetic properiies. Two series of Xonred prostheses were lound to be {erromagnetic. VSM was performed on I6 samples, inclr-:ding ferromagnetic 420F siainless steel. VSM testing was performed using an LDJ model 9600 VSM, in accordance with American Society for Testirrg anrJ Materials standard ,4894. Results: A VSM measures lhe magnetic dipole moment o{ a sample in a magnetic fielcl. The magnetic iield is swept over a range o{ magnetic fie ids, and tl"re magnetic dipole moment is plotted as a functiorr of field. ln a ferromagnetic material, the dipole mcment plat demonstrates hysteresis. The samples made with 3l6L stainless steel, wlrich is used irr otological implants, are fairly non- magnetic relative lo the 420F stairrless stee l. The torque and linear force cln the prosthesis in a given magnetic field can be calculated irom the results o{ VSM. Conclusion: On VSM, prorthe:es made with 3l6L slainless steel were rela* tively nonferromagnstic when r:onrpared with 420! stainless steel. The forees acting on a prosthesis in a given magnetic field can be calculated using VSM" The saiety oi performing MRI in patients with these implants needs to be reas- sessed.

MIDDLE IAR PROSTHISIS DISPLACTMINT IN HICH STRENCTH MACNTTIC FIILDS

Michelle D. Williarns, M.5.4, Pntrickl. Antanelli, M.D., r.A.C.S., nn.d LaynaWilliarns, M.D.

ABSTRACT

Hypothesis: Middle ear prostheses made from nonnragnetic, magnetic reso- ilance (MR)-compatible metals reportedly displace ex vivo in the presence of high magnetic fields used in MR imaging. we postuiated that the prosthesis displacement seen with nonmagnetic, MR-compatible prostheses ex vivo may not be clinically significant in vivo. Methods: Middle ear prostheses made from ferromagnetic (420f stainless steel) and ilonmagnetic MR-compatible metals {3161 siainless steel and plati- num) were examined ior magnetic field inieractions at 4.2 tesla (T)" Ix vivc: testing corrsisted o{ measurements of the translational and rotational motion of the prosthesis irrduced by lhe static magnetic field. ln vivo testing entailed implanting prostheses in cadaveric temporal bones and performing clinical MR sequences. Prosthesis d isplacement was measu red sem iquanti tativeiy. Results: Angular dellection was observed in all samples made from nonmag- netic stainless steel^ The negative control (platinum) demonstrated ncl de{lec- lion, and the positive controls (feromagnelic stainless steel) deflected more than 90 degrees. Torque analysis showed movement in five of five nonmagnetic stainless sleel prostheses. Prostheses made from nonmagneiic stainless steel remained in place without appreciable lor:sening in vivo following MR inrag- ir"r6. Prostheses macie with known ferromagnetic properties were displaced at 4.7 T ht;l not at 1.5 T. Conclusion: Middle ear prostheses nrade from low-magnetic stainless steel do move in the presence of high magnetic fields ex vivo; however, this does not appear to be clinically or statistically significant in vivo at 4"v T. MR imaging shauld be undertaken with caution in individuals with prostheses macJe from slainless steel with strong ferromagnetic properties.

ABSTRACT

Objective: To determine {actors that predict hearing results using a standard prosthesis system. Study Design: Retrospective chart revierv. Setting: Tertiary referral center. Patients: All palients undergoing ossiculr:plasiy wiih the Dornhoffer HAPEX Partial and Total Ossicular Replacement Prostheses (PORP and TORF) from .1999 Iebruary 1!]95 to May who had docLrmenled postoperaiive follow-up and .105 no congenital atresia or stapes fixatiorr. A total of 185 patients (200 ears), men and B0 r,vomen, were evalualed. lntervention{s): Ossiculoplasty with the Dornhoffer prostheses. Main Outcome Measure(s): Hearing resulls using a four-frequency pure-tone average air-bone gap (PTA-ABC) were measured. Mullivariale statistical analy- sis cjetermined the efiect of nrucosal status, ossicular thain status, and type of reconstructiorr techniques on hearing. Results: PTA-ABCs r,r,ere 1 3.4 t 8.1 dB and 1 4,0 t 8.4 for the PORPs (rr * 1 1 4) and TORPs (n = B6), respectively, which was not slatistically different. When the malleus handle was present (n = 125), lhe PTA-ABC was 1 1.6 t 6.2 dB, "16.9 .1il.1 compared to t dB when it was ai:senl ln = 74), which was staiistically significant (P <0"05). Mucr:sal fibrosis, drainage, revision ear surgery, and type af surgical procedure had a significanl detrintental impact on hearing. The type oi pathnlogy (perforation versus cholesteatoma) had no significant inrpact on hearing results. Conclusions: Tlre revised staging system, the Ossiculoplasty Outcome Pa- rameter Stagirrg (OOPS) lnclex, nrore arlequately precJicts hearing oulcome in our series af 200 cases.

ABSTRACT

Obieetive: To study the incidence, pathogenesis, and prevention af delayed facial palsy aiter stapedeclomy. Study Design: Retrc;spective case review. Setting: Otology/neurotology refetral center. Patients: A series a{ 2,152 stapedectomy ptocedures pe rfnrmed in the past 12 years. lnterventian: Delayed {acial palsy after stapedectonly was studied. Main Outcome Measure: House-Brackmann facial nerve grading system and serum antibody titer tests fcr herpes simplex virus lypes I and ll and varicella zoster virus. Results: Delayecl facial palsy occurred in 1 1 of 2,152 procedures. Delayed iacial palsy occurred from 5 to 16 clays (mean, B days) after stapedect6my. Predisposing {aclors were bony facial canal dehiscence, wilh bare facial nerve herniation in 5 patients, cht:rda lynrpani nerve stretchecl, manipulated, or cut in 2 palients, granulomatous reaclion to Cel{oam in I patient, fever blisters on the Lrpper lip in 1 patient, and viral sinusitis in 2 patierrts. Elevated antivaricella titers were iound in all 6 patients studied. Anri-HSV type land ll "riibo,lyantibody tilers were elevated in 5 of 6 patients. Acyclovir was ef{ective in preventins delayed facial palsy in one revision stapedectotny patient, who had delayed facial palsy after prior stapedectonry in the same ear with an elevated anti-HSV antibody titer" Conclusion: Delayed facial palsy occurrecl in 0.51% after stapedectomy. Serologic investigation suggests activation of latent herpesvirus" Mechanical irritalion r:f the facial or chclrda nerve during operation may trigger the activa- tion. The anti-herpes virus agent acyclavir may prevent delayed facial palsy a{ter stapedectomy in patients suspected of this complication.

Objective: Iacial paraiysis can occlrr after surgery for cholesteatoma. The risk af facial nerve iniury is great when the nerve is not covered by its normal bony fallopian canal. The objective of this study was to identify the inciclence oi far:ial nerve dehiscence in patients r-rndergoing surgery for cholesteatcma. Study Design: Retrospective chart review. $etting: Tertiary re{erral hospitai. Patient Population: An assessment r:f all cases pe{ormed hy the senior author fron: I991 1o i 999 identified 59 patients in whom adequate clata were available for analysis. These patients ranged in age from 3 to g2 years" sixty-seven op- erations were performed in total. Intervention: Surgery for cholesteatoma, including tympanoplasty and mas- tnidecton-ry. outcorne kleasures: The presence of facial nerve bony dehiscence aftel exenteration of disease, and postoperative iacial nerve function, Results: Facial nerve bony dehiscence occurred in 33u/, of the total opera- iions analyzed, including 30% r:f the initial surgeries and 35% of the revision surgeries. The dehiscence was present in the tympanic portion of the facial nerve in the vast rxajority of patients. Of the gz,/o at patients with normal preoperative iacial nerve function, all retained normal function postoperatively. Conclusions: Facial nerve dehiscence in our seriEs was far greater than that reported in the literature, underscoring the fact that this is an unclerappreciatec{ finding. Tl"rese findings merit increased vigilance when surgeons dissect near the faci.ri ncrvL,. lntraoperative facial nerve fionitoring has proved to be of value in facial nerve prsservation during acoustic neuroma resections, and mav have a role during sursery for chalesteatoma"

ABSTRACT

Ohjective: lntratympanir: gentarnicin is a well-establisherl and efiective treat- ment for intractable vertigo of a peripheral vestibular etiology. Sensorineural hearirrg krss is a potential complicatinn of the treatment and is directly related to the dose delivered. The risk of hearing k:ss with various treatment regimens has not been clearly delineated. The objective of this study was to establish the risi< of hearing loss and to clarify the relatiorrship between hearing loss and rJrug dose. Data sources: A MIDLINE search of the [nglish literature up to June 1gg9 was conducted using the search ierms inlratympanic, gentantir:iin, vertigo, and Mdni&re's disease. The bibliographies ol each article were reviewed to identify other relevant publ ications. Study Selection: All studies reporting pre- and posttreatment hearing resulls and treatment dose were inclr-rded. The analysis also included the prospectivety collected data from approximately 100 patients treated at ihe authors' institu- tion. Data Synthesis: Pre- and pnsttreatment hearing results were comparecj, and the relatinnship with ireatment dose was explored. Conclusions: lntratympanic gentamicin c;ln be delivered with limited risk to hearing in patients with vertigo oi peripheral labyrinthine origin. ln parienrs with useful hearing, the goal of treatment should be to deliver rl':e lowesr dose of gentamicin that relieves the synrptoms. Some current protccols may use a dose higher thar: necessary for vertigo control and increase the risl< r:f hearing loss.

ABSTRACT

Objective: To assess the impaci of intratympanic gentamicin (ll-C) therapy on the need for invasive surgery (labyrintheciomy and vestibular nerve section) for i ntractable Mdnibre's d isease. Study Design: R.etrospective case review. Setting: Tertiary referral center. Patients: All patients receiving surgical treatment for Mdnibre's disease not controlled by medical therapy, for the 5 years preceding our aderption oi ITC t1987*1991) and the most recent 5-year period (j994*199S). Main Outcome Measures: Type, efficacy, and complications of surgical therapy. -l987 .1998, Results: from thx:ugh 61 patients with intractable Mdnibre's disease underwent labyrinthectomy (.lB patienrs), vesiibular nerve section (2), ITC (29), or endolymphatic sac surgery (12). Although the volume oi surgical cases doubled irom the first 5 years (16) to tlie last 5 years (30), the need for labyrinthectonry drapped from 87.5t'/,. nf cases before ITC to 10% aiter lTC. After the introductir:n of lTC, the use of ITC rose to 67aL, af cases" Of the three patients treated with labyrintlrectomy in the past 5 years, two did not have adequate sLrpport to perform ITC at home or to return for outpatient therapy, and *ne patient wa$ not offered ITC. Vestibular nerve section has not been needed in the past 5 years. Only one patient with bilateral disease reported no imJ:rovement with ITC. Complete or substantial control of vertigo was similar with ITC and invasive ablative techniques (90% vs. 95%). Conclusion; ITC therapy markeclly reduced the need for more invasive ah- lative surgery for intractable M6nibre's disease.

ABSTRACT

Objective: To evaluate issues pertaining to cochlear implantation in patients with far-advanced cochlear oiosclerosis. $tudy Design: Prospective cohort. Setting: Tertiary care referral center. Patients: Iight adult patients (18 years of age or older) reierred for the nran- agement of profound hearing loss, the etiology af which was determined to be otosclerosis. lntervention: Cochlear implantation with a multichannel cochlear implant device. Main Outcome Measures: Benefit from cochlear implant as measured by CID sentence scores, the incidence and management of facial nerve stimulation, and technical issues pertaining to cochlear implantation in this patient popu- la tion. Results: All patients showed signi{icant imprr:vement in auditory {unction as measured by CID sentence scores and ability to engage in lelephone convet- sations. Facial nerve slimulation occurred in two of eight patients and was managed by deactivating the stimLrlating electrodes" Ossification in the basal turn of the cochlea, deiected on preoperative CT, necessitated placement oi the electrr:de into scala vestibuli in two patients and the utilization of a thinner electrode (Nucleus 24) in a third patient. Conclusion: Patients with proiound hearing loss secondary lo otosclerosis derive excellent benefits frr:m cochlear implantation. Surgical implantation can be cr:mplicated by ossification oi the cochlea, which can be detecred on pre- operative CT. Electrode activation may he complicated by facial nerve stinru- lation, which can lre addressed with prr:gramming strategies.

Objective: lrr I998, clinical trials were initiated to evaluate tlre Clarion pre- curved electrr:de plus Electrode Positioning System (EPS) in adults witlr severe "I999, io ptofound hearing impairment. ln clinical trials were initiated to assess the Clarion HiFocus Electrode plus EPS in a sirnilar group of adults. This retro- spective study evaluated the benefit of these new electrode designs and com- pared the postoperaiive speech perception abilities oi 60 patients implanted with the precurved e lectrode * IPS and 43 patients implanted with the HiFocus electrode r EPS. Study Design: All subjects participated in preoperative testing with hearing aids and postoperative testing ("1 montlr and 3 months) with either the precurved electrode + EPS or the HiFocus electrode + tPS. Ilemographic characteristics and pre- and postnperative speech perception results were compared within and between the two groups. Setting: Ths clinical trial data presented here were collected at 26 cochlear implant programs affiliated with tertiary medical centers located in the United States and Canada. Patients: Postlinguistically deafened adults who received a Clarion cochlear implant" Results: Speech perception results demonstrate the improved ccmmunication benefit provided by these two electrode designs when comparecJ with resulis ohtained preoperatively when using conventional ampliiication. A comparison of demographic data showed that the HiFocus €lroup had a significantly longer duration of deafness than the precurved electrode group. Statistical comparison of speech perception abilities showed no significant difference between pa- tients using the precurved electrode + IPS and those using the HiFocus elec- trode + [PS, aithough the mean anrJ rnedian scores for word and sentence recognition were higher ior the HiFocus + EPS group.

ASSTRACT

Hypothesis: The size oi the jugulotympanic paraganglionra {JTP) is directly related to the density oi Ki-67 antibody- and c-fo.s antibody-la[:eled cells, and is indicative of tumor aggressiveness" Background: Jugulotympanic paragangl iomas are usually slow-grerwing be- nign tunrors of the temporal bone; however, some tumors may show aggressive growth rates and l-:econre malignant" ln this study, we utilized c-fcsand Ki-67 antibodies for labeling cells in the active phase of replication. The density of c-fos- or Ki-67-labeled cells was compared to tumor size for determining a possible relationship to the rate of growth. Method: Nine surgical tumor specimens that included both the glomus tym- panicum (CT) and glomus jugulare (CJ) were investigated using immunohisto- chernical ancJ ultrastructural analysis. Tumc;r sections Iabeled with Ki-67, c-fos, y-tubulin, and S-100 antibodies were analyzed using a light nricroscope inter- faced with a computer-based mapping system. UltrastructLrral arralysis of the tumor sections was performed to cr:mpare morplrological {eatures. Result: Large-sized and recurrent glomus tumors (most aggressive types) had a higher density of Ki-67- and c-tos-labeled cells with a low density r:f the ry-tubulin-laL;e lEd cells than the small-sized nonaggressive tumors" 1n addition, rnalignant and recurrent glomus lumors had an increased numlrer of mitochon- dria as compared to the small-sized tumors. Conclusion: There is a positive correlation l:elween the aggressiveness of glomus tumors and the density of Ki-57- and c-fr:-s-labeled cells, but a negative correlation for density cf 1-tubulin-labeled cells. An increased number of cel* lular organe lles suclr as mitochondria might reflect the rapid tumor growth rate. We conclude that Ki-67 and c-fos antibodies are indicative of a faster growth rate and susceptibilily for recLrrrence in glomus tumors.

Stilianos E. Kottyttskis, M"D., Plt,D., lohn Skoultts, h,4.D., Dintre Phillips, M.5., snd C. Y.loseTth Chang

ABSTRACT

Obiective: To identify pctential risk iactors {or neonatal hearing loss that are not included in the current varial:les recognized hy tlre Joini C.ommittee on lnfant Hearing (JCIH). Methods: A series o{ conser:ulively born r:eonates with risk factors {or hearing loss based on the 1994 JCIH registry were screened prospectively. There were 110 subjtcts with hearing loss and 636 sulrjects without hearing ioss. Data collected as poie ntial risk faciors for infant hearing loss included not only those on the JCIH list but also others that we be lieved could be significant. The iniant hearing screening was performed on each subl'ect using auditory brain stem testing. Statistical analysis of data was performed using the chi-squared lest. Results: ln addition to the variables listed by the JCIH, we identiiied 'tl other risk {actors that were associated with hearing loss in our neonatal populaticn: length of stay in the iniensive care unit, respiratory distress syndron":e, reirolen- tal fibroplasia, asphyxia, nleconium aspiration, neurodegenerative disorders, chromosomal abnornralities, drug and alcohol abuse by the motirer, maternal diabetes, mLrltiple births, and lack of prenatal care. Conclusion: This study identified f i risk faclerrs in addition to those currently on the high-risk registry published by the lClH for neonalal hearing loss. The inclusion of these additiorral risk {actors in neonatal screening programs may inrprove the detection rate of neonates with hearirrg loss. Further study will be needed to determirre whelher^ inclusion of these additional risk factors in a hearirrg screening program can provide an eflicacious allernative to the use of univcrsli irr[ant st rcening.

ROLI OF IMACINC IN THE CLINICAL DIACNOSIS OF INNER IAR DISORDIRS

Araind Kunlnr, !\4.D", Mnhmood Mnhfee , M.D",Scotf W. DiVentrr., M.D., and Hcm Soo Bae, B.S.

ABSTRACT

Obiective: ln the clinical setting af unilateral hearing loss, unilateral tinnitus, dizziness, and facial paralysis, modern imaging lras effectively served to "rule out acr:ustic tumor." However, in the mafority of patients, no tumor is found, arrd tho caustl of the symptoms renrains unclear. This stLrdy sought to demon- strate the diagnostic potential oi advanced imaging studies for disorders of the inner ear and adjacent nerves. Study Design: Retrospective case review. Settingr Tertiary referral center. Patients: lndividuals presentirrg with Lrnilateral hearing loss, unilateral tinni- tus, dizziness, and/or facial paralysis. lnterventions: Diagnostic review of palients' clinical, audiologic, vestibular, and imaging studies. Main Outcome Measure: Comprehensive clinical data in patients with uni- lateral inner oar symptoms were correlated with results of advarrced imaging. Methods: Comprehensive clinical clala are correlated with the results of ad- vanced imagirrg studies, and specific inner ear diagnoses were established. Examples of such diagnoses include hemorrhage intc the inner ear, cochlear derrdritic demyelination, cochlear otosclerosis, inflammatory lesions r:{ the me- aial and intralabyrinthine f;lcial nerve and inner ear, intralabyrinthine schwannoma, and endolymphatic sac tumor. Conclusions: When advanced imaging of the inner ear is correlated with conrprehensive clirrical data, speci{ic pathologic entiiies of the inner ear can be tonfidently diagnosed. Should all patients with unilateral inner ear symptoms undergo this cr:stly imaging procedure? More data are needed to answer the question. A multicenter study o{ patients with unilateral inner ear symploms would prcvide data that coLrld be used in developing;lppropriate guidelines.
